This application comprises a continuat on in part of applicants co-pen-ding application Serial Nm 400,064 filed July 30, 1920. I

My invention relates to sockets and more particularly to shock-absorbing sockets for usein radio apparatus. One ofthe objects of my invention is to provide an improvedshockmbsorbing socket,. a which will be durable and fetlic'ient inuse,

.simple in-construction and cheap to manu- .-facture.
